If you look at the wiki page for strcmp, the third parameter is 'ignorecase'. You can ignore case sensitivity in the names, so for example, if you logged on with the name "ken" as opposed to "Ken", my code would ignore case sensitivity and it would still know you're Ken, despite the fact that you haven't capitalized the 'K' at the beginning of your name.

The SA-MP wiki has details like this for (almost) every native function.
